Yelena Belova Leads New Avengers in Marvel's Upcoming Film Avengers: Doomsday

Marvel's forthcoming movie *Avengers: Doomsday* (scheduled for Dec. 18, 2026 and directed by the Russo brothers) features the Thunderbolts rebranded as the New Avengers. The team is led visually by Florence Pugh’s Yelena Belova, joined by Red Guardian (David Harbour), Bucky Barnes (Sebastian Stan), Ghost (Hannah John‑Kamen), the U.S. Agent (Wyatt Russell) and the powerful Sentinel known as Bob (Lewis Pullman).

Concept art released for the film shows the group as an official hero unit, marking a shift from their previous anti‑hero status. While Marvel Studios has not officially confirmed a leadership change, the presence of two rival Avengers teams – Yelena’s New Avengers and Sam Wilson’s team – sets up a narrative clash that could determine future MCU leadership.

The speculation highlights Yelena’s background from the Red Room as a credible factor for her new role, and emphasizes that the Sentinel’s near‑limitless power may be crucial against a heightened Doctor Doom in the story.
